FOXD1 and neoplasm: More importantly, results revealed that the tumor volume and weight from mice treated with DDP were decreased in FOXD1‐AS1‐inhibited AGS cells relative to shCtrl‐transfected AGS cells, suggesting that tumors with low FOXD1‐AS1 level were more sensitive to DDP treatment than that in shCtrl+DDP groups (Fig. 7A,B).
